Hello,
What would you advise me if I need to determine the start and end of constant lines in the chart?
Thank you.

Hello,
I want to view in one chart :
- the time progress of the parameter
- the control levels - value of parameter must not exceed these levels

These levels can be a different value at different time intervals - see picture const_lines.png.

Best Regards,
Daniela

Hi Daniela,

If this is a categorical axis (e.g. you don't provide X values to the line data points then the values should be the catgorical index of the start / end points [0, 3] in the case of the first line. Otherwise if this is a DateTime scale should pass in date time values converted to double - using ToOADate():

double startValue = startDate.ToOADate();

Hope this helps - let us know if you meet any problems.
